What is the approximate amount of fresh Atlantis Truffles which would be equivalent (in psychoactivity) to fresh and dried Psilocybe Cubensis respectively?


This question is very interesting, regarding the fact that potency of mushrooms or truffles can vary greatly from one batch to the next. And then, storage and drying conditions also have a strong impact on the potency. Last but not least, there’s your own sensibility to this psychoactive plant, which can vary greatly from one person to the other. 

So talking about dosages, dried or fresh, is always a bit tricky. 

But if the following considerations are taken into account, we are able to compare dosages. Just keep in mind that it’s a general dose, and the effects of yours may still be different. Don’t say we didn’t warn you 😉

  • Our (indoor cultivated) truffles come from the same supplier so potency is regulated over the batches. 
  • On the internet you can find plenty of information on how to properly dry and store magic truffles and mushrooms
  • Have a precision scale at hand for measuring your dose. 


Fresh Atlantis truffles


5 to 9 grams – normal trip
10 to 15 grams – strong trip

Dried Atlantis truffles


2,5 to 5 grams – normal trip
5 – 7,5 grams – strong trip

There is no reliable way of converting weight in grams from fresh to dry. Fresh truffles contain approximately 50-70% water (i.e. 10 grams fresh = approximately 5 gram dry). 

Fresh P. cubensis mushrooms

5-10 grams – light trip
15-25 grams – medium to strong trip 
30-35 grams – trip of the highest level for true psychonauts.

Dried P. cubensis mushrooms



1 to 2,5 grams – normal trip
2,5 to 5 grams – strong trip

There is no reliable way of converting weight in grams from fresh to dry, mushrooms contain approximately 90% water (i.e. 10 grams fresh = approximately 1 gram dry) but the figure varies from species to species. 

We highly recommend to read more on dosages , storage and effects. For example, check our encyclopeadia entries on magic truffles and Psilocybe cubensis (magic mushrooms).  

Furthermore, Erowid has reliable information on Psilocybin contents
